Thanks. We r using goats milk. Stud is in Canada. We r n Florida!! Went to vet today. Mom has toxic shock of all things. Passing on to puppy, hence GI issues. Mom is n hospital. Puppy getting new meds from vet and doing better. Only formula feeding now of course. Please keep momma dog n your prayers. She is very sick. Puppy seems to be thriving well at this point. He is a tough little guy. Thanks for all the answers and caring words.
